Definitions

  • the present invention relates generally to door assemblies and, more particularly, to overhead sliding door assemblies and associated interior paneling for airplanes.
  • Overhead sliding passenger doors are commonly employed in the main passenger doorways of commercial airliners. Such a door is opened by raising it upwardly over the doorway on tracks affixed to the inside of fuselage. The raised door is thereby stowed out of the way in an overhead position. The door is ordinarily passed through an opening in the cabin ceiling and stowed out of sight in an overhead space above the ceiling.
  • the overhead sliding door is particular ly suited to an airliner because the curved contour of the fuselage conveniently accommodates the similarly curved door , enabling the door to fit closely against the inside of the fuselage during opening and closing.
  • the primary advantage over a conventional hinged door is that the overhead sliding door does not have to be swung open inwardly into the occasionally crowded passenger cabin area, or swung outwardly in an awkward manner by an oper ator standing inside the airplane. Examples of overhead sliding door assemblies are disclosed in U.S.
  • Patents No. 4,106,729 to Bergman et al. and No. 3,802,125 to Baker which are hereby incorporated by reference.
  • Another particular problem to which the pr esent invention is directed is the stowage of an overhead sliding door in the limited overhead space available in medium-sized airliners having fuselages of relatively small diameter .
  • the overhead stowage space in such airliners for example a Boeing 767 airplane, is crowded with control cables, ducting, electr ical wiring, lights and other items. Under such conditions, it has not been feasible to provide a simple trap door in the ceiling through which the cbor and its associated interior panels can be raised, as has been done in larger airliners having a larger overhead stowage space.
  • a combined door and interior cabin panel assembly that includes a pr esentable panel closure member for the overhead opening of the cabin ceiling when the door is in its closed position, and which also allows the door to be opened inwardly and raised upwardly through the opening to a stowed position above the cabin ceiling. More particularly, it is an object to provide such a assembly wher ein a set of foldable cabin panels are coupled to the door and adapted to fold upwardly out of the way as the door is opened.
  • It is also an object to provide an overhead sliding door and pan el assembly that includes a movable inter ior fuselage panel that covers the fuselage wall above the doorway when the door is closed, and which is movable upwardly out of the way when the door is raised.
  • the present invention is dir ected to a combined door and interior panel assembly for an exter ior doorway of a convexly contoured vehicl e fuselage, such as that of an air plane.
  • the door and panel assembly is par ticularly adapted for a vehicle having an interior cabin ceiling extending horizontally within the fuselage body.
  • the assembly includes an overhead sliding door and a set of foldable interior panels coupled thereto. The door travels on tracks affixed to the inside of the fuselage.
  • the door is movable between a closed position, occupying the doorway, and an open, stowed position wherein at least a major portion of the door is located above the ceiling.
  • the foldable panels are configur ed to close the opening in the ceiling with the door in the closed position, and are coupled to the door so as to fold upwardly out of the way into the overhead space above the ceiling as the door is raised to its stowed position.
  • the foldable panels also cover the fuselage wall immediately above the doorway when the door is lowered to its closed position.
  • the entire assembly forms an effective and presentable closure system for both the doorway in the fuselage and the opening in the ceiling. With appropriate counterbalance tensioning to assist in raising the door, the door and foldable panel assembly can be easily opened and closed by an operator with a single, uninterr upted movement.
  • the foldable panels include an inboard ceiling panel, an outboard ceiling panel, and a side panel.
  • the three panels are hinged together edgewise for relative folding motion. With the door closed, the side panel covers the fuselage wall over the doorway and extends upwardly to the opening in the ceiling.
  • the outboard ceiling panel is hinged to the upper edge of the side panel and covers the outboard half of the ceiling opening.
  • the inboard ceiling panel is hinged to the outboard ceiling panel along a fore and aft hinge line so as to cover the Inboard half of the ceiling opening.
  • the inboard ceiling panel is pivotably coupled on its Inboard side to the cabin ceiling for upward swinging motion.
  • the panels When the door is raised to its stowed position, the panels ar e engaged with the door through a lost-motion coupling mechanism and folded upwardly into the overhead space above the cabin ceiling.
  • the opening in the ceiling is closed when the door is raised by a lower por tion of the door that is adapted to presentably cover the ceiling opening.
  • the ceiling opening is closed when the door is lower ed as well as when it is raised.
  • the door moves between a closed position in the doorway and a stowed position wher ein the door is raised upwardly into the overhead space above the cabin ceiling.
  • the door tracks guide the door first inboard sever al inches to clear the doorway and then upwardly along the inside of the fuselage wall.
  • the side panel remains relatively stationary and the door slides upwardly past the side panel.
  • the side panel becomes engaged and tr avels upwardly with the sliding door.
  • the ceiling panels being hinged to the side panel, ar e likewise carried upwardly into the overhead ceiling compar tment once the side panel is engaged with the door.
  • the ceiling panels are swung upwardly away from the opening in the ceiling and stowed compactly adjacent the door .
  • the sequence is reversed when the door is closed, with the door sliding downwardly over the doorway and the ceiling panels unfolding and swinging into the ceiling opening.
  • the side panel tr avels with the door until the ceiling panels are nearly covering the ceiling opening, at which point the side panel stops as the door continues downwardly.
  • the door continues moving downwardly and then outwardly to its final closed position in the doorway.
  • the side panel and the ceiling panels are locked into their r espective positions over the door and in the opening of the ceiling.
  • the door and panel assembly thus far described is particularly suited to a door having an escape slide container such as that described in the above-referenced patent to Bergman et al.
  • the escape slide container can be configured to form a presentable closure member in the ceiling opening when the door is raised.
  • the combined door and interior panels form an attr active and functional assembly that is automatically stowed in the overhead ceiling compartment when the door is opened and automatically deployed into position when the door is closed.
  • the foldable panels In their deployed positions with the door closed, the foldable panels presentably and protectively cover the ceiling opening and the fuselage wall over the doorway.
  • the escape slide container on the door forms a pr esentable and effective closur e member in the ceiling panel. All of this is accomplished within a minimum of overhead compartment space and with all mechanical movements being linked to the door for simplicity and reliability of oper ation.

  • the side panel is also free to rotate slightly as the door 26 rises. In this r egard, the door 26 rotates about a fore-and-aft axis because it follows the curved contour of the fuselage.
  • This rotation of the door 26 causes the side panel 54 to undergo the same rotation and thereby causes the rollers 81 to tr avel inwardly along the overhead horizontal tracks 84 to the open inboard ends 84a, as shown in FIGURES 4 and 10.

Abstract

L'assemblage supérieur de porte coulissante et de panneau repliable intérieur est particulièrement adapté pour des avions de ligne ayant un plafond bas et un espace supérieur limité pour permettre le dégagement de la porte au-dessus du plafond de la cabine. L'assemblage comprend un jeu de panneaux repliables de cabine (50, 52, 54) qui fonctionne pour couvrir l'ouverture de plafond supérieur (28) lorsque la porte (26) est fermée. En ouvrant la porte (26) en la faisant glisser vers le haut le long de rails (30, 32) au travers de l'ouverture de plafond (28), les panneaux repliables (50, 52, 54) sont engagés par la porte (26) et basculent vers le haut et vers l'intérieur avec la porte dans l'espace supérieur au-dessus du plafond (22). Inversément, les panneaux repliables (50, 52, 54) sont remis en place pour couvrir l'ouverture de plafond (28) lorsque la porte (26) est abaissée en la ramenant dans sa position fermée dans l'encadrement de porte (25). La porte (26) et les panneaux repliables (50, 52, 54) sont adaptés pour occuper un minimum d'espace dans le compartiment de dégagement supérieur de manière à permettre le passage de câbles de commande, de conduits et d'autres éléments dans le compartiment supérieur. Dans le mode préférentiel de réalisation, la porte (26) comprend un conteneur intégral de coulissement de dégagement (26c) adapté pour former un organe de fermeture présentable dans l'ouverture de plafond (28) lorsque la porte est relevée dans sa position dégagée supérieure de sorte que l'ouverture de plafond soit effectivement fermée, que la porte se trouve dans la position fermée ou que la porte se trouve dans la position ouverte.
